FB 620/780/790 - Radial Fine Boring Heads
Designed for all types of fine boring operations, the radial type FB 620, FB 780 and FB 790 heads cover a broad diameter range and allow for precision adjustments within microns. The insert holder and head contact protect the micrometric diameter setting on these tools for increased reliability. These factors combined produce down to IT5 hole tolerances and excellent surface finishes.
Ideal for low-to-average machine speeds, the FB 780 line covers a 15 – 205 mm diameter range and includes nine pre-balanced cutting heads. Developed for high-speed machining, the FB 790 line covers a 30 – 115 mm diameter range and includes five balanced cutting heads. FB 780 and FB 790 fine boring heads are available with Graflex® and Seco-Capto connections.
Compact FB 620 radial fine boring heads feature a GL or a BA machine side connection, making them the perfect match to Steadyline® vibration damping turning and boring bars. They cover a diameter range from 34mm to 115mm.
All of the radial fine boring heads are dust proof and never require any re-greasing, which helps promote long tool life. These coolant-through heads come in three insert holder sizes and a large range of insert grades to accommodate a wide variety of workpiece materials.
